Question

我是openstack环境的新手，我正在尝试使用Openstack API。我在执行基本脚本以使用neutron API列出网络时遇到以下错误。

脚本

#!/usr/bin/env python
from neutronclient.v2_0 import client as neutronClient
import os

neutronConnection = neutronClient.Client(
    username=os.environ['OS_USERNAME'],
    password=os.environ['OS_PASSWORD'],
    tenant_name=os.environ['OS_TENANT_NAME'],
    auth_url=os.environ['OS_AUTH_URL']
    )
print neutronConnection
neutronConnection.format = 'json'
neutronConnection.list_networks()

错误

    neutronConnection.list_networks()
  File "/usr/lib/python2.6/site-packages/neutronclient/v2_0/client.py", line 98, in with_params
    ret = self.function(instance, *args, **kwargs)

Answer 1

该错误表示您在OS_TENANT_NAME环境变量中传递的租户名称存在问题。它的价值是“ESS”，并且没有具有该名称的租户，或者用户无权访问它。

如果您能够运行neutron CLI，请打印出您在那里使用的环境变量并将其复制到您的代码中。
